200k unconfirmed transactions

what happens if a bitcoin transaction is not relayed

At some moment, unconfirmed transactions can be an unpleasant surprise when sending Bitcoin from wallet to wallet. We will tell you how to solve this problem. The issue of unconfirmed transactions came to a head in December during the peak of the cryptocurrency craze.

Due to the double whammy of overloaded exchanges and constant DDoS attacks, a whopping number of , Bitcoin transactions remained unconfirmed for over a day. Notably, the Ethereum network had similar problems after CryptoKitties caused havoc with its Mempool. Although, as it later turned out, this was an extremely frontloaded success, and the killer dApp is yet to appear on the horizon.

A more recent example of a rapid increase in the level of network congestion was related to the Bithumb hack in June. Most probably, the delays and the increased fees were connected to the South Korea-based exchange cleaning out its wallets.

Bitcoin is a cryptocurrency that is based on the Proof-of-Work PoW algorithm. All Bitcoin transactions are conducted with the help of cryptocurrency mining.

However, for a given payment to be processed successfully, it has to be confirmed by a miner who gets a block reward for each confirmation. Until confirmed, it remains in the mempool. Ethereum, on the other hand, had this issue resolved by adjusting the blocksize to the network volume.

That is why the Ethereum network was able to handle a three-times-bigger transaction volume back in February. As of now, the blocksize is limited to 1 MB this limit was introduced by none other than Satoshi Nakamoto. These record block sizes were made possible by transactions with numerous segwit inputs created on BitGo with super low fees.

Block rewards are the bread and butter of cryptocurrency miners. Long story short, this is the place where all unconfirmed transactions remain in limbo. The pool unites all the computers that are connected to the Bitcoin Network with the help of Bitcoin mining software. All payments that are yet to be confirmed are stored in the RAM of a given device. If the mempool size is inching closer to occupying the whole RAM capacity, the node is able to automatically discard all pending requests with lower fees.

It is worth pointing out that the mempool is not a queue — different nodes have their own set of transactions that to be confirmed, and they are clearly incentivized to pick transactions that have the highest mining fees. The more popular BTC gets, the bigger is the size of the mempool. Would better hardware make a difference?

The modus operandi of the Bitcoin network presupposes that each block is mined every ten minutes or nearly so , and the same timeframe would remain in place even if every miner had a chance to be equipped with super powerful hardware. In order to get all the insights into the current state of the mempool, one simply has to visit the website of a German software engineer Jochen Hoenicke: it displays all current Bitcoin fees along with the current mempool size.

The most obvious way to get to the top of the mempool and get your money transfer confirmed is to pay a higher fee. During the Bitcoin boom in December, some users would have to pay a jaw-dropping 40 percent fee in order to send a single payment.

However, how to make sure that your fee is high enough for your transaction to be confirmed? It is not always reasonable to accept any fee that is automatically suggested by your wallet software.

There is a website called bitcoinfees. As mentioned above, the transactions that are going to pay less in fees are going to be processed first. The dark blue line indicates the number of transfers that went through the mempool — it clearly shows how much money people paid to get their payment completed. All high priority transactions appear in the green area.

Those who want to save money can go for a lover fee, and they may get their transaction processed relatively fast if they get lucky and the whole mempool gets cleaned out in a snap. Is there a way to get out of this predicament for those individuals who are not willing to shell out higher fees? Still, there are certain workarounds that will help you confirm your transaction faster even with lower fees:.

Do not send your payments during the time of day when the Bitcoin network usually experiences the highest level of congestion. Join the Roger Ver crowd, and switch to any other altcoin. Litecoin, Bitcoin Cash, and other top 10 entire have faster payments and lower fees, but there is a roadblock in the form of poor merchant adoption. On the right, you can see the delay in minutes that shows how long you have to wait to get your transaction processed. How many confirmations do you need?

It actually depends on the size of your payment. Crypto bulls will have to go through a whopping number of confirmations before getting their millions, which is fair enough.

The particular number of confirmations also depends on the exchange of your choice. For instance, Coinbase, the most popular fiat-to-crypto exchange in the world, requires three confirmations before any payment is completed. On top of that, there is a direct link between confirmations and the digital asset of your choice. Before taking any further steps, you have to check whether your transaction is confirmed or not. Pick any Blockchain explorer for instance, Blockchain.

If your transaction remains in limbo for a prolonged period of time, there are three ways to find a way out of this predicament:. Continue waiting for your confirmation it may up to a week for your transaction to get confirmed. Alternatively, you can simply sit and wait until your transaction expires after being dropped from the mempool.

Lastly, one can also replace an already existing transaction through Replace-By-Fee. Notably, Satoshi was the one who came up with this idea buy later he decided to shelve the fee replacement feature. Later, it made a comeback with Bitcoin Core 0. Still, this practice gets constantly slammed by the BTC community due to the fact that allegedly destroys trust in transactions that remain in the mempool.

The thing is, one can use this feature voluntarily: the sender can easily disable it, so there is no need to be concerned about trust issues. Uninitiated Bitcoin users should refrain from canceling unconfirmed Bitcoin payments in such a way!

One should keep in mind that all BTC transactions are irreversible that why you should check all transaction information extra carefully. With that being said, it is impossible to cancel your Bitcoin transaction since there is no single centralized authority that presides over them.

In fact, BTC is supposed to be the very first digital currency that has managed to solve the double-spending problem. The Bitcoin network prevents this with the help of cryptographic techniques. When it comes to unconfirmed transfers, however, there is a loophole for those who want to double spend. The revelation was made by Reddit user Peter Todd who proved that unconfirmed Bitcoin transactions are not safe due to some differences in mining software. Child-Pays-for-Parent something that reminds of a welfare program is actually an example of one of the solutions to the great Bitcoin scalability problem.

CPFP allows a receiver to broadcast the same transaction but with a different fee, thus propelling low-fee transactions to the top of the mempool.

At Coinbase , all stuck payments are carried out with the help of the CPFP protocol, effectively tackling one of the most debatable issues on the Bitcoin network. The difference between RBF and CPFP presupposed that in the latter case miners — as the name of the protocol implies — confirm a parent transaction. Rational-thinking miners have to confirm a cheaper transaction in order to include a hefty one in their block. The bottom line is that RBF is a viable option for those who want to confirm their transactions faster by increasing the amount of the fee.

Meanwhile, CPFP is more suitable for a sender who fails to persuade the miner to pay a transaction fee instead of him. While the actual number of Bitcoin keeps increasing, the network itself is less clogged with the relatively low number of unconfirmed transactions. In the peak on the Bitcoin network was recorded on Dec. Notably, the decrease in strain on the network coincided with the release of Bitcoin Core 0. However, the update is not related to the issue of unconfirmed BTC transactions despite the actual announcement mentioning certain changes pertaining to transaction handling.

Although the past few months have seen an increased number of unconfirmed transactions. The peak came in June when Bitcoin showed annual records, then the number reached 55 thousand. Now the situation has largely changed and the average number of transactions does not exceed 5 thousand.

LN, launched on 26 December , has already gained widespread adoption. The modus operandi of LN consists of transferring Bitcoin off-chain, which is supposed to solve the slowness of the Bitcoin network — the transaction is conducted on a separate channel that is created by two traders.

The launch of LN conveniently coincided with a sharp drop in transaction fees almost 50 percent , but there is not enough data to determine the exact effect of LN. Most likely, the aforementioned drop in fees was caused by the dramatic crypto rout that started in January. As of Jul. SegWit segregated witness posed as a solution for unclogging the Bitcoin network.

Together with the block size of SegWit allowed to significantly increase network bandwidth. The technology has been already adopted by major cryptocurrency exchanges such as Coinbase and Bitfinex. Nevertheless, SegWit still accounts for only 0. Hence, it would be logical for retailers to adopt zero-confirmation transactions and off-chain transactions to accelerate the purchasing process despite the risks of double-spending. As mentioned above, the main purpose behind confirmation is to avoid the much-feared double-spending.

Meanwhile, the Bitcoin Cash community is already mulling over accepting zero-confirmation BCH transactions in order to give a competitive advantage to the network. Speaking of further innovations, a recent Forbes article suggests that Bitcoin needs a better consensus algorithm that is superior to the current Proof-of-Work PoW. The system requires a minuscule amount of Proof-of-Work. The scalability issue continues haunting Bitcoin.

How many Bitcoin Confirmations are Enough?

A transaction first has trandaction be verified by the network. It is gradually passed round the network and each full node checks to see whether, subject to certain criteria, it is a valid transaction. When the transaction is verified it is then placed in a transaction pool. At this point the miner then selects — up to the maximum block size — a number of transactions from the pool. Transactions are chosen by priority which is defined as larger trades and oldest trades — so the older the transaction and the larger the transaction the more likely it is to be picked out of the pool.

The first 50 kb of any block is set aside for high priority transactions, otherwise the miner can just choose the largest number of transactions with fees — and low value old transactions would never get processed. Any transactions left over would sit traansaction the pool ready to be picked up and hashed into the next block. The transactions chosen would then be fed into a Merkle tree and used transaciton all the other required data by the miner to find a solutio n.

If a solution is found the miner then sends the solution and all its required data to its neighbouring node who then checks the calculations, and if they are correct, forwards it on to its neighbour. However, if two solutions are found at the same time a fork can occur in the Bitcoin blockchain — or basically a temporary variation across the network.
